问可以用CakePHP3在插件中创建插件吗？

EN

Plugin::load('Themes', ['bootstrap' => true]);

<?php

use Cake\Core\Plugin;

// load the red and blue child plugins
Plugin::load('Themes/plugins/Red');
Plugin::load('Themes/plugins/Blue');

"autoload": {
    "psr-4": {
        "App\\": "src",
        "Red\\": "./plugins/Themes/plugins/Red/src",
        "Blue\\": "./plugins/Themes/plugins/Blue/src"
    }
}

php composer.phar dumpautoload

public function initialize()
{
    // load (supposedly-existing) components from the "Red" or "Blue" themes
    // load GradientComponent of the "Red" theme
    $this->loadComponent('Red.Gradient');

    // load ColorComponent of the "Blue" theme
    $this->loadComponent('Blue.Color');

    // use what you asked for...
    $this->Color->someMethod(['data']);

    parent::initialize();
}

public function beforeRender(Event $event)
{
    // use the "home" layout from the Red theme
    $this->viewBuilder()->setLayout('Themes/plugins/Red.home');

    parent::beforeRender($event);
}
